Sourcing Cluster Guide · Industrial
China's largest bicycle city — tens of millions of bikes and e-bikes a year, from kids' 12-inch to cargo e-trikes.
Tianjin is China's largest bicycle and electric-bicycle manufacturing base. The Wuqing, Beichen and Jinghai districts host hundreds of assemblers and component suppliers, and the municipality accounts for an estimated 40% or more of China's bicycle output. Annual production across bicycles and e-bikes runs into the tens of millions of units, exported worldwide — traditionally strong in entry-level and mid-market segments, with a fast-growing premium and e-bike capability.
The cluster is built around component density: frames, forks, wheels, drivetrains, saddles, batteries, motors and controllers are all made locally, and Shimano's Tianjin plant anchors the mid-range drivetrain supply. That is why a 500-unit order of a 27.5-inch alloy MTB or a 250 W city e-bike can be produced in 35–45 days at a landed cost well below European assembly. Battery pack assembly and BMS programming are also local, with Samsung, LG and Chinese cell options.
For buyers, the key risk in Tianjin is specification drift on e-bikes: motor wattage, battery capacity and controller limits are frequently overstated, and EN 15194 compliance is claimed rather than tested. Lock the motor and battery part numbers, require a capacity discharge test and a full EN 15194 test report naming the model, and inspect weld quality and paint adhesion before loading.
Trial order: 100–300 pcs per bicycle model, 50–100 pcs for e-bikes, mixed models in one 40'HQ. Lead time 35–45 days for stock frames, 55–70 days for custom paint or new tooling. Require a full EN 15194 (or ISO 4210 / CPSC) report naming the exact model, a battery capacity test and 100% pre-shipment function check; we verify weld quality, paint adhesion and torque values.
